JOHN P. POLNASZEK, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR OF ONE-HALF TO iANDRE L. BINET, OF ROBBINSDALE, MINNESOTA;

GRAIN-CAR` STRUCTURE. l

Application filed April 19, 1926. Serial No. 102,844.

Thisfinvention relates' to boit'V car con-- struction and especially toan attachment for facilitating the removal of grain d-oors employedinstandard box cars.

lt is the main object of this invention to provide an extremely simplebut highly eiiicient box car construction or attachment therefor, which-will quickly deliver the grain within a car adjacent the grain doors ateither side of the car, thereby permitting the grain doors to be readilyremoved without becoming damaged.

A further object of the invention is lto through the bottom thereofadjacent thel doors and slidable gates for closing or opening saidpassages adapted to be operated from without the car and normally heldin closed position. v l

A still further object is to provide in combination with this device, adelivery chute` for each passage, adapted to drop the grain attherespective sides of the car in the usual grain pits. t

These and other objects of the invention will be apparent in thefollowing description'made in connection withl the accompanyingdrawings, in which like characters refer to similar parts throughout theseveral views, and'in which Figfl is a fragmentary side elevationof aportionof aboX car made in conformance with my invention.

Fig. 2 is a cross section on the line 2 2 of Fig. 1. f

Fig. 3 is .avertical section taken on the line 3-3 of Fig. 2.

Fig. 4 is a detail cross section of one of my devices on a larger scaletaken on the line 1 4 of Fig. 1 and showing my device sealed up forshipment, and

Fig. 5 is a fragmentary cross section of my device showing theconnection of the operating handle with the gate.

A preferred embodiment of my invention is shown in combination with astandard freight car of the boXtype. The car comprises the sides 6having the usual door ways formed in the central portions thereof, andsupported on the longitudinally extending central beams 7 and the sidebeams 8. The bottom of the car is indicated by the nu# meral 9 and a'grain door of any suitable construction is indicated by the numeral 1()f mounted within one of the door ways.

I preferably rrecess the sides of the car bottom 9 centrally of the doorways to aord a pair of rectangularpassages immediately adjacent thegrain doors 10 when the latter are employed. On the sides of each ofthese passages guidel means are formed, preferably by securing angularbars 11 to the edges of car bottom 9 labout said passages.

Angular bars llvcarryinwardly projecting ltongue portions 11 formingrectangular flanges in the inner ysides of each of the pas,- sages. Agate'designated as' an entirety A normally closes each of the passagesdescribed and comprisesv an upper rectangular plate 12 and a lowerrectangular plate 13 riveted or otherwise secured to plate 12 andprovided at'its edges with downwardly and outwardly curvedpflanges 13,the edges of plate 12 and flanges 18at are spaced apart to.snuglydengage the tongues 11a on angle bars 11, whereby slidableengagement is made be tween gates A and guides 11. Angle bars 11 may beinsetv slightly on the car bottom 9 whereby the top plate 12 of gates Amay be maintained Hush with the upper surface of bottom 9. inasmuch asthe passages are formed by recessing the side edges of the floor 9, itwill be seen thatmy gates may be withdrawn outwardly ofthe car.

Secured to the bottom plate 13 of each of the gates is an inwardlyextending armor link 11i preferably carrying at its inner end an eye 15,to which is secured one end of a coiled spring or other elastic member16. Spring 16 may be secured at its other end to one of the central'beams 7 thereby resiliently holding the gate in closed position. y Anoperating handle 17 .is secured by means of a chain or other flexiblemember 18 to the front end of each of the gates, facilitating theopening thereof from `without the car. Beneath and on the inner side ofeach of the passages described I provide a hood or delivery chute 19 ofpreferably segmental form, adapted to direct the grain )downwardly andoutwardly and dropping rso description, butmayibe brieflyy summarizedas'folloivs:

llVlienit :is-desired to unload the grain cai'. the handle1 lmaybepulled, thereby permitting the'grainV in the central portion of the carad'acent the Orain doorto be withdrawn. y r ,b 'm v Woor 'three minutesis 'sunici'ent time to yrenio've" a A"substantial"portion oir' the`'grain pressing against the grain door. The grain door may 'be 'thenHreadily removed Without destro'yiii'gthe 'same as V'is the usual custom.After the grainadoors are removed the automaticshovels"may be employed'and 'fthe car unloaded'in theusual manner.

2rEhe time factor in destroying the grain door is an importantfone, asvW'ell as the Waste and expense of providing new grain d'oforsf'torevery'sliipment. 'My device pei'- mitslthe' car'tobe rapidly unloadedWithout impairingin any Way :thegrain doors Veinployed. i

As'has Vbeen stated, the grain delivered throughl'the hoods 19 isdropped at the side of the car and into the'usualfgrain.pits.

A'lt will benoted thatmy gates 'A eniploy'ed, overlap lthe tongues llasuliciently to Storm leak proofclosuresior thepassages and are moreoverresiliently heldin closed position by thesprings 16.

Fromthefabove descriptionit Will be seen that I have'invented a highlyefficient improvement'in box car construction, which may be readilyapplied as an attachment for standard box cars noiv inl use, and `whichwill accomplish results' heretofore runat tained.

' lt ivill, ot course, be understoodthat various changes maybe made iinthe forni, details, arrangement and 'proportions of the parts, rWithoutdeparting from the scope of applicaiits invention Which, generallystated, consists in a `device capable of carryway adapted to receive agrain door, said car -havingfa floor opening immediately adjacent saiddoorway, a delivery chute eX- ftending.downwardly and outwardly fromsaid floor opening, a gate horizontally iiiovable. across .said openingand outwardly from the doorway of said .carimeansforiiormally holding'said .gate inwardly in closed ,position, and means yfor openingsaid-gate from ivithou .said car', .whereby:material in the carpressing: against the grainidoor maybe.
